I have a chinese ebay T3 on my bug and have over 20,000 miles on it to date this year alone! works fine. I have had Garrett turbos come apart and nothing went through my motor put on another one and good to go, If the Chinese turbo explodes inplodes what ever ill bolt on another. I do not personally know anyone that has had a Chinese turbo failure so far.
i'm on the second e bay t3t4 on a 2.3 ford,runs 20 psi, and yes the bushings got clogged up with burnt oil so the unit failed.the new setup has a better drainback hose,runs 22lbs now no failure in 5 months so far....
